running Tor relay live with AddressSanitizer
by starlight.2013q4＠binnacle.cx 28 Jun '14

28 Jun '14

Has anyone tried running a live relay with an image built using GCC 4.8 and -fsanitize=address? AddressSanitizer documentation says it should be no worse than about x4 on CPU and typically about x2, so it looks reasonable to try. I'm seeing peak CPU of about 7-8% of a 2.2GHz AMD core. I'd probably create a static build, with 'libevent' and 'tor' compiled using -fsanitize=address -O1 -fno-omit-frame-pointer -g per the Google documentation and 'libz' compiled normally since 'zlib' is stable … [View More]

Need help to get TorDNSEL compiled
by BlueStar88 26 Jun '14

26 Jun '14

Hi there, today I've read about the outage at "check.torproject.org". Since my torcheck-service "torcheck.xenobite.eu" needs the underlying TorDNSEL feature I'm trying to get this to work on my host. Like this I won't need to query the TorDNSEL-part of "check.torproject.org" anymore. I'm not into programming and do not know anything about haskell, c++ and such. So be patient with me on such matters. ;-) I've DL'ed the code from the internet website mirror [2]. I've prepp'ed all the … [View More]

Setting up AWS cloud-relay - don't reserve expensive storage!
by Nick Sheppard 31 Mar '14

31 Mar '14

Hi all, I set up an AWS EC2 cloud Tor relay a month ago and made an expensive mistake. Perhaps others may learn from my example! I followed the instructions on the tor-project website, and found that it actually is quite a simple process, as it says. I did notice that the AWS setup screens I was seeing were different from the screenshots on the website, but they were asking me similar questions so I just went with the defaults where the website said "No changes". I didn't look … [View More]

External connections to port 9050
by Greg W 24 Mar '14

24 Mar '14

I turned on some logging on my firewall today to help troubleshoot and issue and noticed a load of connections from external addresses to port 9050 on my exit node. I don't think that should be publicly accessible. Am I wrong about it being publicly accessible and does anyone else see lots of connection attempts on that port? Thanks, Greg

Problem encountered with Bandwith Authority algorithm (was : "bandwidth authority algorithm is cracked")
by julien.robin28＠free.fr 03 Mar '14

03 Mar '14

Hi everybody, 15 days, 16 hours and 15 minutes (without any restart) have passed since my 2 involved in this problem are restarted (started at the same time). And there is something very clear and interesting to see. They both have restarted from nearly zero (~100kB/s) in the first days, and a problem is still completly present on 1 of the 2 identity : -> The first one (the older one also) is stuck at less than 1MB/sec (5,510 in consensus weight) - ArachnideFR94 -> The second one is … [View More]growing, growing and growing, now around 9MB/sec (and more than 75,000 in the consensus weight) - ArachnideFR94v2 It can be very clearly seen by observing graph on Tor Atlas. (But there is no more bandwith earthquake like I had on december.) On this machine, the first daemon is launched by /etc/init.d, while the second one is manually lauched via another non-admin user. No differences, same nice value, completely the same torrc file apart from nickname, DirPort, ORPort and MyFamily. Pretty large max bandwith for both of them : RelayBandwidthRate 25600 KB RelayBandwidthBurst 122070 KB ShutdownWaitLength 90 -- Into the log file : The only one difference was this (I just corrected it) - it was on the server that is working perfectly fine (ArachnideFR94v2) : Jan 30 06:07:03.000 [warn] Failing because we have 4063 connections already. Please raise your ulimit -n. [6978 similar message(s) suppressed in last 21600 seconds] Jan 30 12:07:17.000 [warn] Failing because we have 4063 connections already. Please raise your ulimit -n. [20004 similar message(s) suppressed in last 21600 seconds] -> Oops :s I know very well this problem and I just forgot to prevent it this time - Sorry for that - Corrected by editing /etc/security/limits.conf and adding some lines about the user used by my second tor daemon - I just restarted this one by SIGINT, wait and new launch (logged with a much better ulimit !) today at 12:35 UTC. Absolutely nothing else abnormal into the log of the 2 daemons. And the problem of ulimit was on the one that runs perfectly well! -- Any idea of why the first one is completely stuck at such a low value ? The next steps would be to set the 2 tor daemons on the /etc/init.d using the Multiple Tor Processes example at www.torservers.net on this machine, and to watch if ArachnideFR94v2 launched by /etc/init.d is still working as well as today. If no solution appears, may be trying to re-install the entire system, and watch what happens would be interesting. If still no solutions, it will be complicated to understand ! Best regards, and thank you in advance for your ideas Julien ROBIN [View Less]

is comcast throttling relays?

Hey, I am running the following relay, and never see traffic going more than 250k. Is Comcast throttling non-exit tor proxies? https://atlas.torproject.org/#details/7E6183143778259F025576A5803E3334AB95C…

Effects of Rebooting?
by Tor Relay 28 Feb '14

28 Feb '14

I am a n00b relay (OnionTorte) operator, and, as such, know lamentably little of what I'm doing. (Yes, I'm one of *those* relay operators.) When I went to bed last night I had an HSDir flag, but it has since disappeared. And since this A.M. my consensus was halved. A bit of promiscuous pokings-about in relay metrics leads me to think that this happened in the wake of my having had to reboot my machine to unwedge it. Speed Test shows that even on the worst of BadHair Days my u/l speed … [View More]
